sub 1mbps up/down high latency and packet loss - wired TW2

Internet speed, latency, and packet loss has degraded rapidly over the past two days in the TW2 area. Using the SuperHub 3 in modern mode connected to a TP-Link Archer A7 AC1750 has worked fine for 3 months.

200 | 20 mbps package - Typical 221 | 21 mbps - Currently getting 2.5 | 0.7 mpbs, often down as low as 0.5 | 0.2 mbps per thinkbroadband, speedtest (ookla), uswitch, etc. (Wired, gigabit)

Ping statistics for 8.8.8.8:
Packets: Sent = 6571, Received = 5789, Lost = 782 (11% loss),
Approximate round trip times in milli-seconds:
Minimum = 9ms, Maximum = 117ms, Average = 15ms

Average ping is typical, maximum is around double, and the packet loss percentage is unacceptable. (Wired, gigabit)

Performed multiple reboots of both the SuperHub 3 and Archer A7 and disconnected all other devices from the network to perform testing.

Likely a bad line or noise on the segment.

With any luck VM team will look into this and not ask you to put hub in router mode for tests they can do in modem mode.

You can setup a BQM

Already have a BQM but this site doesn't seem to like me posting everything in one go. Was trying to also post the router stats but.. yeah not a great forum.

BQM

Re: sub 1mbps up/down high latency and packet loss - wired TW2

Hi there @jackjt8

 

Thank you so much for your post and I am so sorry to see you are facing these issues with your Hub! 

 

I have been able to locate your account with your forum details and can see that there are a few issues showing on your Hub! For this reason I think it would be best to get an engineer out so they can take a look directly for you. 

 

I will send you a PM now to arrange this, please keep and an eye out for the purple envelope in the top right corner of your screen alerting you to a new message. 

 

Thank you.

Re: sub 1mbps up/down high latency and packet loss - wired TW2

What issues have you identified with the Hub? It is setup correctly in modern mode as it's WiFi is poor (expected) and an external Archer A7 is used to handle WiFi. We have not faced any issues till recently.

Re-asking here as it may be useful for other users to know about said solutions

Likely docsis low SNR or power levels and maybe some T3 timeouts

Re: sub 1mbps up/down high latency and packet loss - wired TW2

The booked engineer arrived on time; bit of miscommunication where the engineer was told it was for a WiFi issue. After relaying the SNR issue to the engineer it went smoothly.

Issue identified as being SNR caused by the network from the pit outside tested straight from the tap bank. Effecting multiple customers (around 6) connected to the same pit. Network team has been called out so hoping within 48 hours we will have this resolved.

Update - Network team was out around 11:30 and managed to resolve the network issue and restored the SNR but the speed was still not improving. Between 2pm and 5:15pm there was periodic latency spikes every 20 minutes or so. By 6pm full 210-20mbps speed restored

Interesting your speed was not fixed when packet loss was fixed...maybe VM router knows your having packet loss and slows you down then does a check with the modem every number of hours and speed is restored?

Re: sub 1mbps up/down high latency and packet loss - wired TW2

Hello @jackjt8,

 

Welcome back to the community page, thank you for posting on here.

 

I am sorry for the packet loss and the lack of connection.

 

I would love to help you further, I located your account using your forums details and checked the Hub, I can see some errors that need investigating. I will need to book an engineer for you, I will send you a private message so I can make sure I have the correct account and person 🙂

 

Please look out for a plum envelope at the top right of the page.

 

Many thanks,

Hayley
